I know you would need to add a ton of lubricant but around here the stuff is cheaper than diesel for some reason. Has anyone tried mixing 80% kerosene with 20% fryer lard in one tank? (it wouldn't allow the engine to preheat first without a second tank) I have been sloshing around the idea of getting two tanks but I really don't want to spend the cash to take out my new 32gal and sub in two expensive 16gallon tanks. Is there any reasonable way to add a small 2nd tank on a 6.2 suburban that already has a rear tank?

I have tons of sources of grease but no good way that isn't a pain in the arse or expensive to use it.

I can easily get kerosene but I'm not sure what to add to make it safe to burn.

Also does anyone have a kit for a suburban to burn grease (not biodiesel) I'm curious how a 6.2 suburban handles the stuff.

Optiminal solution would be a kit with the three port fuel switch, preheaters, racor stainless steel filter, 2nd fuel tank, heater fuel lines and the works. I wouldn't want to install it though.

Thanx for any ideas

Hi I have been a hd mechanic for 40 yrs and International used to recommend adding your used engine oil to your winter fuel for lubrication, as artic fuel is basically the same as kerosene. We were running rosamaster fuel pumps at that time which are basically the same pump as you have on the 6.2. The biggist problem you can run into is plugging your fuel filter or I have seen where it lays on the bottom of the fuel tank and causes problems.Make sure it is mixed well with the fuel. Hope this helps you out.

Didn't Mercedes use to recommend putting automatic transmission fluid in to lubricate the pump in their old diesels?

it will burn hotter and you will get lower mpg, but it will save you money in the short run. http://img3.harmony-central.com/acapella/ubb/smile.gif

rmay, I have been burning waste vegetable oil for 2 years in my 89 Ford 7.3, and about a year in my 89 GMC G20. But the GMC has not been used much at all. Note I burn "waste vegetable oil", not grease. "Clear Fry" Cooking Oil is what I look for, nothing else. It is well filtered.

I have burned straight 100% WVO in the Ford most of the time. However I have decided to stop burning 100% VO. Reading about the history of using these oils as diesel fuel has convinced me that burning 100% WVO, SVO (straight vegetable oil), RVO (recycled Vegetable oil), or VVO (virgin vegetable oil) will waste a diesel sooner or later. At present I am using 50/50 or stronger in my diesels. This winter I will use 20% WVO, maybe less if fuel problems start happening. Using a VO blended with heating oil should work fine. Mike
